Setting mysql innodb-buffer-pool-size (2 replies)

I need to increase my innodb-buffer-pool-size to 1G. When I try to do this from the desktop icon->MySal->mySql settings->innodb-buffer-pool-size->Size->Choose
I see that I can set it to
Enter Size: xxxx followed by M for Mega or G for Giga The symbol M or G must be attached to the number. For example : 64M ; 256M ; 1G

But if I type 1G I get an error message "The value you entered (1G) is out of range.
The number must be between 10 and 9999.
The number must be followed by M (For Mega) or G (For Giga)
The value is set to 128M by default."
This seems illogical...

If I to the change manually in the my.ini file: innodb_buffer_pool_size = 1G and restart Wampserver, the change is not taken into account!
